If you cancel your club card, your Club membership will be cancelled too (it won't stay through March 2018).
Instead of cancelling, you can call and "downgrade" to a
no-annual-fee card (or the Explorer card if you want that). You'll still lose your club membership, but I'm 95% sure you'll get a prorated annual fee refund in this case.
